:huh: I just installed the free Simple Image Gallery plugin (and activated it) that is needed in order to be able to use the k2 images gallery functionality. Unfortunately, it still displays an error message that tells me I have to install the plugin! Does this functionality only work with the commercial version? Please advice,
regards Lydie Polak

Hello Lydie,

The K2 Gallery functionality requires the Pro version of Simple Image Gallery Pro.
It is available here: www.joomlaworks.net/extensions/commercial-premium/simple-image-gallery-pro

Alternative you can try our Inceptive Image Gallery for K2 here

extend.inceptive.gr/shop/k2-extensions/i...mage-gallery-for-k2/

which does pretty much the same thing.
